PRODUCTS
LifeSize Gateway series consists of the following products:
Gateway-PRI (see About the Gateway-PRI)
Gateway-Serial (see About the Gateway-Serial)
ABOUT THE
GATEWAY-PRI The Gateway-PRI enables audio, video, and data communication between
H.320 endpoints that connect through ISDN, and H.323 endpoints that connect
through a packet-based network. For voice-over-IP, the Gateway-PRI enables
PSTN voice callers to connect from the ISDN network to IP voice callers. The
Gateway-PRI supports two PRI ISDN ports.
ABOUT THE
GATEWAY-SERIAL The Gateway-Serial supports multimedia conferencing over IP by translating
between H.323 and serial protocols. With the help of an Imux, the LifeSize
Gateway can also translate between H.323 and H.320 protocols.
The LifeSize Gateway offers a serial leg for multimedia conferencing over IP by
providing an interface for legacy endpoints with serial interfaces,
encryption/decryption devices, satellite networks and leased line services.

FEATURES Table 1-1 lists the major features of the LifeSize Gateway.
Table 1-1 Gateway Feature Summary
Feature Description
Interoperability The LifeSize Gateway provides a high degree of
interoperability with other H.323 compliant gateways,
gatekeepers, terminals, proxy, and Multipoint Control
Unit (MCU) products by being based on the H.320
standard and H.323 protocol stack.
Web-based management The LifeSize Gateway features the LifeSize Gateway
interface. This is a web interface used to configure and
monitor the LifeSize Gateway. You can view and modify
all aspects of the LifeSize Gateway configuration from a
remote location using a Java-enabled web browser.
SNMP management The LifeSize Gateway features Simple Network
Management Protocol (SNMP) management that
supports all aspects of monitoring, diagnostics,
configuration, and trapping.
Diagnostics The LifeSize Gateway features front and rear panel LED
indicators that display status for the unit. You can also
access remote diagnostics of the unit through the
LifeSize Gateway interface, Telnet, SNMP, or a serial
port.
Network load balancing The LifeSize Gateway supports load balancing on the
network by communicating with a gatekeeper through
H.323 RAI (Resource Available Indication)/RAC
(Resource Available Confirmation) messages.
T.120 data collaboration The LifeSize Gateway supports data transfers in calls
between ISDN and IP by using high speed T.120 in
HMLP and VarMLP formats.
Quality of service (QoS) The LifeSize Gateway features configurable coding of
media packets to achieve QoS routing priority on the
Internet Protocol (IP) network. The Type of Service
(ToS) bits of the IP datagram header can be configured
for priority level.
